Retrain Categories
Use the CategorySetTraining action to retrain a category. You can use text, documents, a Boolean expression, and category content or a combination of these to retrain a category. When you retrain a category, its original training merges with the new training. For example:
http://IDOLhost:port/action=CategorySetTraining&Category=323499876022105571056&Boolean=dog AND NOT cat&BuildNow=true
In this example, IDOL server retrains the category with the ID 323499876022105571056 using the Boolean expression dog AND NOT cat. The BuildNow parameter instructs IDOL server to build the categories immediately so they become active. You can also activate the category later using the CategoryBuild action.
